All we've got going at the moment is the Compiler Construction Toolkit.
Compiler Construction Toolkit is a collection of web-based tools that automate some of the tedious, error-prone aspects of compiler design. It's not as rich as ANTLR, but it's very accessible and provides immediate gratification:
- Nothing to download or install. Works online.
- Input as JSON, so you can dump objects from your favorite language to form input.
- Syntax highlighting and auto-indentation courtesy the awesome Ace editor.
